Another option is to switch the guest to Xen PVH mode. The Grub2 PVH
image can boot LZ4-compressed kernels and all versions of Ubuntu
that use LZ4 kernels also support booting as a PVH mode guest
without any change to the guest.
grub-mkimage -O i386-xenpvh -o /opt/grub/lib/pvhgrub.bin …
I am not sure that you will find anyone to work on Xen PV support
any more as I think Xen upstream would rather see you move to PVH.
Cheers,
Andy
